SEATTLE (AP) — The Seattle police department says two of its officers have been arrested for suspicion of a hit-and-run and driving under the influence.

Seattle police spokesman Sean Whitcomb says a local resident noticed a collision just after midnight Monday, saying that a woman driving a Nissan Altima had front-end damage. The witness said the woman stopped the car and switched seats with a male passenger and they drove off.

Whitcomb says officers did an area check and found the Altima a few blocks away, parked two to three feet away from the curb with the engine still running. Officers recognized the pair in the car as off-duty police officers.

A duty captain responded to the scene and the pair was arrested.

Investigators aren’t sure yet what the pair struck while driving.
